Whether a defendant "willfully" violates the federal antistructuring statute merely by knowing of a bank's currency-reporting obligation and deliberately structuring transactions to avoid a report.
Holding
No. To convict under §§ 5322(a) and 5324(3), the Government must prove that the defendant knew that structuring transactions to evade the reporting requirement was itself unlawful.
Reasoning
Section 5324 prohibited structuring transactions for the purpose of evading a financial institution's obligation to report currency transactions exceeding $10,000. But the separate criminal-penalty provision, § 5322(a), imposed criminal punishment only on a person who "willfully" violated § 5324. Reading the offense as requiring only knowledge of the reporting duty and an intent to avoid reporting would leave the statutory term "willfully" with no independent work to do. The Court declined to treat an express element of a criminal statute as surplusage.
The meaning of "willfully" depends on statutory context. Throughout the same Bank Secrecy Act subchapter, courts had read § 5322(a)'s willfulness requirement to demand more than intentional conduct: the defendant had to know of the pertinent legal duty and deliberately disobey it. Because § 5322(a) is one omnibus penalty provision governing several related reporting offenses, the Court found strong reason to give its willfulness requirement a consistent meaning when applied to the antistructuring provision.
The Government argued that a purpose to evade reporting itself supplied the bad purpose required for willfulness. The Court rejected that argument because structuring is not inevitably or obviously criminal. A person might divide cash deposits to avoid an IRS audit, reduce the risk that information about personal wealth could lead to burglary, or conceal assets from a former spouse. Those motives may be objectionable or lawful depending on the circumstances, but they show that transaction structuring is not inherently so blameworthy that Congress could be assumed to have dispensed with proof of knowledge of illegality.
The Court relied on the statutory text rather than conflicting legislative-history materials suggesting that Congress intended a lesser scienter requirement. Even if the text were ambiguous, the rule of lenity would require resolving that ambiguity in the defendant's favor, because criminal statutes must provide fair warning and legislatures—not courts—must clearly define criminal conduct.
This interpretation did not create a general ignorance-of-the-law defense. Rather, Congress may make knowledge of illegality an element by using "willfully" in a particular statutory setting. Here, the jury was never instructed that it had to find Ratzlaf knew structuring was illegal, so his conviction could not stand.
